If the magnetic dipole of an atom of diamagnetic material, paramagnetic material and ferromagnetic material are denoted by $\mu_d, \mu_p$ and $\mu_f$ respectively, then:
  1. $\mu_d=0$ and $\mu_p \neq 0$
  2. $\mu_d \neq 0$ and $\mu_p=0$
  3. $\mu_p=0$ and $\mu_f \neq 0$
  4. $\mu_d \neq 0$ and $\mu_f \neq 0$

Solution

$\mu_{\mathrm{p}} \neq \mu_f \neq 0$ and $\mu_a=0$
